' 2 Claims. (CI. 20-49) -This invention relates to window constructionsof the double-hung type wherein the sash slide vertically with respectto the window frame. It pertains more particularly to a windowconstruction wherein the sash may be moved pivotally with respect to theframe, in addition to their sliding movement, so as to provide forventilation and also to dispose themso that the outside surfaces of thewindows may be conveniently Washed.

The primary object of the invention is to provide a window constructionof the character referred to wherein the upper and lower sash membersare pivoted to elements slidable in the window frame, the sash andslidable elements having interlocking means rendering the jointstherebetween weatherproof and also preventing pivoting of the sashmembers. outwardly of the frame while they are positioned for ordinarysliding movement.

Another object of the present invention is to provide manuallyreleasable means for holding the sash members against pivotal movementinwardly of the frame when such movementis not desired, the means'beingso constructed that it has a comparatively large area of contact withthe window stops so as to eliminate possibility of forcing the windowinwardly, either by wind pressure or bypersons attempting to gain.unauthorized entrance through the window into a building. In otherwords, the largeness of the bearing surface of the means referred towith respect to the window stops practically precludes the possibilityof forcing the said means through. the window stops even though thelatter are formed of comparatively narrow wood strips according toconventional practice. In addition to providing a large bearing surfacethe means referred to also provides for weatherproo-fing inasmuch as itcloses spaces above the slidable members which otherwise would permitthe entrance of air.

With the above and other ends in view the invention is more fullydisclosed with reference to the accompanying drawings, in which Figs. 1,2 and 3 are vertical sections illustrating different positions ofadjustment of the sash members;

Fig. 4 is a fragmental section of the frame and sash;

Figs. 5 and 6 are top plans of the means for preventing the sash frompivoting;

Figs. 7 and 8 are elevations of said means, and

Fig. 9 is a fragmental section illustrating the sash pivot.

Like characters of reference are employed throughout to designatecorresponding parts.

In-the drawings the numeral i designates a window frame having spacedstops 2 secured thereto and extending vertically thereof, each stophaving a groove 3 extending throughout the length thereof. Slidablebetween the pairs of stops 2 are side rails 4, each side rail beingformed of sheet metal and having a tongue 5 slidably received in thegroove 3 of the adjacent stop 2, reference being had more particularlyat this time to Fig. 4. From the tongue portion 5 the side rail has anintegral portion which extends parallel to the inner face of the stop 2,as designated at 5, thus providing a surface for sliding engagement withthe stop. The wall 6 as viewed 7 in. cross section terminates at thegroove formation I, which is disposed inwardly of the inner surface ofthe stop 2, and a tongue formation 8 is provided at the inner side ofthe groove. The tongue formation 8 is supported by a wall 9 extendingtherefrom in the direction of the main body of the rail 4 which contactswith the inner surface of the frame member I. At the other side of therail 4 a wall l extends inwardly of the window parallel toand in contactwith the other stop 2 and the wall l0 supports a tongue l.

The sash member I 2 has a metallic member I 3 of substantially channelform secured thereto, the member l3 having a groove formation itnormally receiving the tongue 8 and a tongue formation l5 normallyreceived in the groove 1. At the other side of the sash [2 the member I3has a groove formation It normally receiving the tongue ll.

Referring to Fig. 9, the metallic member l3 has a comparatively heavymetal reinforce l1 secured thereto, as by Weldinggand supporting a pivotpin I8. The pivot pin I8 is preferably in the form of a rivet. The lowerend of the rail 4 has a protuberance formed inwardly thereof with ametal reinforce 20 secured thereto and receiving the other end of therivet l8. Themembers 4 and I3 are thus pivotally connected together sothat they may be relatively moved in order to permit movement of thesash to the various positions of adjustment illustrated in Figs. 1, 2and 3.

Due to the interlocking engagement of the several tongues and groovesabove described, the sash is prevented from being pivoted outwardly ofthe frame i. This interlocking engagement also provides forweatherproofing of the joint between the rails and sash. Additionalweatherproofing is provided for by a channel member 22 which is nestedwithin. the rail 4 in sliding engagement with the walls 9 and I thereof.Springs 23 normally press the channel-shaped sealing member 22 intoengagement with the surface of the metallic member I3.

To restrict pivotal movement of the sash in.- wardly of the window toany desired extent links 24 are pivotally attached tothe sash and havepins 25 slidable in slots 26 in the channel members 22, a wall of eachslot having a series of spaced notches 21 adapted to receive the pins25. By engaging the pins in different notches the sash may be held. inan inclined position for ventilating purposes, such as shown in Fig. 2,a horizontal position for ventilating or washing purposes as shown inFig. 3, or it may be held at different positions ranging between the twoextremes illustrated.

Referring to Figs. to 8 inclusive, there is illustrated means forholding the members l3 against pivotal movement with respect to theirrails l so that the sash may be moved vertically in the customarymanner. This means comprises an angle bracket having a portion 28secured to the top surface of the meeting rail 29 by screws or otherfastening elements 30, and a portion 3| extending downwardly in contactwith the outside surface of the sash member l2. At each side of thebracket portion 3| are formed hinge parts such as shown at 32 and plates33 are hingedly connected to the bracket portion 3| by such hingemembers. At the top of each plate 33 is a wall 34 formed with a slot 35receiving a pin 36 on a head 31. The head 31 is connected to a slidingbolt 38 in such manner that the latter is free to rotate with respectthereto. The boit 38 is slidably received in the substantiallycylindrical guide member 39 on the bracket portion 28. The guide 39 hasa lengthwise extending slot 40 through which an actuating pin 4|extends, and one of the side walls of the slot is provided with notches4'2 adapted to receive the pin 4| in such manner as to prevent the boltfrom moving lengthwise with respect to its guide.

As illustrated in Figs. 5 and 7 the bolt 38 is in a position holding theplates 33 projecting from the sash and engaging adjacent stops 2. Whenso positioned the sash is free to move vertically of the frame butcannot pivot with respect thereto.

In Figs. 6 and 8 the bolt is in a position holding the plates 33parallel to the edge of the shaft and removed from between the stops 2,and the sash is free to pivot with respect to the frame.

Although a specific embodiment of the invention has been illustrated anddescribed it will be understood that various changes may be made withinthe scope of the appended claims without departing from the spirit ofthe invention, and such changes are contemplated.

What I claim is:

1. In a window structure including a frame, a movable window sash,channel-shaped side members receiving side portions of said sash andhaving opposite surfaces disposed toward adjacent sides of the frame,each of said side members having a longitudinal groove between saidsurface and said frame along one vertical edge of the sash and having asecond longitudinal groove along the other edge thereof, channel-shapedmembers interposed one between each of said first named channel shapedmembers and an adjoining side of the frame and closed by said surfaces,each of said second-named channel-shaped members having border portionsof its opposite longitudinal edges positioned for sliding movement insaid grooves.

2. In a window structure including a frame, a movable window sash,channel-shaped side members receiving side portions of said sash andhaving opposite surfaces disposed toward adjacent sides of the frame,each of said side members having a longitudinal groove between saidsurface and said frame along one vertical edge of the sash and having .asecond longitudinal groove along the other edge thereof, channel-shapedmembers interposed one between each of said first namedchannel-shapedmembersand an adjoining side of the frame and closed bysaid surfaces, each of said second-named channel-shaped members havingborder portions of its opposite longitudinal edges positioned forsliding movement in said grooves, stop members, and side members eachhaving a tongue along one edge thereof positioned in one of said groovesand having a tongue along the other edge thereof positioned for slidingmovement in a groove in an adjoining stop member.
